Abstract
The studied trees of coniferous plant species are characterized by high rates of genetic diversity (P. sylvestris: P95 — 0,914; na — 1.914; ne — 1.356; HE — 0.230; I — 0.369; L. sibirica: P95 — 0.988; na — 1.989; ne — 1.272; HE — 0.192; I — 0.327). The 7 acids were found in samples of Scots pine resin, and 4 acids were found in samples of Siberian larch resin, among them abietic and dehydroabietic acids. The content of abietic acid in samples of Scots pine varied from 3.78% to 13.69%, and dehydroabietic acid — from 10.26% to 33.80%. In Siberian larch, the content of abietic acid is higher (from 5.07% to 29.85%), and dehydroabietic acid is lower (from 1.49% to 8.18%). A correlation was found between the genetic diversity of the studied samples of Scots pine and Siberian larch and the content of abietic and dehydroabietic acids in them.
